Solar flare hit the Earth

The particles ejected by the sun in recent days in a flare and a coronal mass ejection, (for its acronym in English) hit Earth's magnetic field after 9:00 pm on Tuesday, the U.S. space agency (NASA .)

Radiation, plasma and other particles came from an ejection type M8.7, the second most intense within the classification of solar events. According to the Climate Prediction Center Space Administration National Oceanic and Atmospheric Administration (NOAA) of United States, the solar flare occurred on Sunday 22 and then produced a CME that made her the strongest radiation storm since September, 2005.The Goddard Space Flight Center NASA predicted that the CME could generate some auroras and perhaps affect the operations of some satellites and communications on shortwave radio, but pose no harm to human health.

According to Alejandro Lara, Institute of Geophysics (IGF) of the National Autonomous University of Mexico  solar flares of recent days to Mexico will not affect the configuration of its magnetic field as it is not as exposed to these shocks because of its proximity to Ecuador, in contrast to areas near the poles.

They are also completely normal and expected events, because that Andrea Borgazzi, space geophysics, the Sun goes through regular cycles of activity and every 11 years or so there is a peak, which had already been delayed.

At that peak storms typically occur sometimes deform and even pass through the Earth's magnetic field, but generally the atmosphere protects these effects, except that the intensity and quantity of particles is such that causes changes in the magnetic field.

"The Earth has a magnetic field or geomagnetic field lines interact with the solar ejection lines, if the ejection have correspondence with them is a phenomenon called magnetic reconnection that alters the telecommunications spectrum," explained the researcher also Institute of Geophysics.

The SWPC, which is part of NOAA, has distributed images of the Sun in which several of these spots identified with numbers, and an image which shows a huge flash in the area of ​​spots 1401 and 1402.NOAA detected a flash last Thursday and one on Sunday, followed by shock waves of billions of tons of plasma traveling at about 8 million miles per hour.

The wave caused by the second of two flashes reached Earth about 34 hours later, instead of two or more days that usually take this shift, according to NOAA scientists.

Among the factors involved in the geoefectividad of solar storms on Earth are the speed of the shock front, the particle density and magnetic field orientation.
